Dust Bowl on the Llano Estacado

The Dust Bowl was an environmental catastrophe, a natural hazard (multiannual drought) in the 1930s in the Southern Great Plains of the USA, resulting in the activation of a geomorphic process (intense wind erosion) which, when human society could not adapt to it, cascaded into unprecedented agricultural, economic, and societal collapse in its core region. Over the years, the cause of the Dust Bowl has been variably ascribed to specific climatic or meteorological phenomena or land management practices. Drought and wind erosion have been notable phenomena in the Southern Great Plains throughout the Holocene, occurring long before conversion of the land to agricultural use, and still continue today. (Gill and Lee 2006)

History of the Llano Estacado

I have suggested many times that ecology plays an important role in the history of a region. The history of the Llano Estacado is certainly no exception. In order to understand the history of our region we need to study the effect of ecology on the lifestyle and settlement patterns of the Native Americans, the exploration and settlement patterns of the Spaniards, and the ultimate settlement patterns of the Anglo-Americans. Enjoy.

South East Asia

Although we will not start our in depth study of SE Asia until next month I thought that it might help to show you a few maps that will hopefully help us to become oriented.

Map of SE Asia

This map superimposes a map of the Indonesian Islands over the map of the continental US. I find that this map helps me to get a better understanding of the size of the region.
Remember that Malaysia is about the same size as New Mexico.
